I've never QT CUC. TBH I don't have the space to setup a seperate frag tank to use as a QT for inverts. The fish QT was on my kitchen table as it was lol.Read through your whole thread, nice looking tank and setup!
One question, you said you were going to take things slow and QT properly, and I saw you did that with your fish successfully. Any reason you didn't QT your CUC?
